Gelato Drand VRF
Verifiable public randomness on chain
The problem Gelato Drand VRF solves
Fair random numbers on-chain for all applications (e.g. DeFi, GameFi, lotteries...)
Challenges we ran into
The drand proof is a BLS-12-381 signature which is not supported natively on most Etherea. We are looking into zero-knowledge proofs to alleviate this.
If multiple applications use the same random seed, there can be interactions. To avoid that, we require applications to supply a unique salt to combine with the drand output.
